Bearing Seals Caravan and Boat Trailers

Bearing seals for caravan and boat trailers keep bearing lube intact, ensuring the proper function of wheels.

Seals for trailers and caravans are one of the axle system’s most important—yet often forgotten—components. This is because you’re in serious trouble if your seal fails.

We only sell seals with a spring on the inside lip of the seal. (excluding Holden LM Seals) Look for this spring before you install your hub or drum. Sometimes, you’ll pop it right out—if you knock it into position with too much muscle.

Some Key Info On Your Bearing Seals

The spring provides a little tension on the rubber lip of the seal against the axle journal. Neither low-quality seals nor marine seals have springs to provide this tension.

As a result, marine seals are a tight fit on the axle and fit loosely into the steel housing in the disc or drum. Consequently, these seals push firmly against their axle shoulders.

We make most of our quality bearing seals from metal casting and include a spring inside the seal. This spring puts pressure on the lip of the seal to ensure a tighter fit into the axle seal journal.
